[0023] Please see Figures 1 to 3 The processing equipment provided in this application includes a processing head 10 and a processing head ranging component 20, which is mounted on the processing head 10. The processing head ranging component 20 includes a bracket 21, a detection element 22, a drive assembly 23, a pusher 24, a guide shaft 25, and a trigger 26. The bracket 21 is used to mount the processing head 10. The detection element 22 is located on the bracket 21. The fixed end of the drive assembly 23 is fixed to the bracket 21. The pusher 24 is fixed to the movable end of the drive assembly 23. One end of the guide shaft 25 is fixed to the pusher 24, and the other end of the guide shaft 25 is movably connected to the bracket 21. The trigger 26 is located on the guide shaft 25. Initially, the drive assembly 23 is in a retracted state, and the pusher 24 is located above the nozzle of the processing head 10. The drive assembly 23 can extend relative to the bracket 21 to push the pusher 24 out, thereby allowing the pusher... Located below the nozzle of the processing head 10, the pusher 24 is used to compress the drive assembly 23 under the pressure of the workpiece when the processing head 10 drives the support 21 toward the workpiece to be processed. It also drives the guide shaft 25 to move relative to the support 21 to the trigger 26 to trigger the detection element 22, so that the detection element 22 detects that the processing head 10 has moved into place, and then controls the processing head 10 to stop at that position for processing. That is, this solution uses the support 21, drive assembly 23, pusher 24, guide shaft 25, trigger 26 and detection element 22 to achieve precise distance measurement of the processing head 10 in a mechanical way, which can solve the problem that the traditional capacitive distance measurement method cannot achieve distance measurement in the flame laser composite cutting scenario.

[0024] The processing head 10 can be a cutting head, welding head, etc., and is not limited to it. In this embodiment, the processing head 10 is used as a cutting head for example.

[0025] In this design, the trigger element 26 is a pressure block, and the detection element 22 is a micro switch. After the processing head 10 reaches its designated position, the trigger element 26 moves under the drive of the guide shaft 25 to press the detection element 22, thereby causing the detection element 22 to detect that the processing head 10 has reached its designated position. It is understood that the detection element 22 can also be other detection sensors such as a proximity switch, magnetic switch, or photoelectric switch, with the trigger element 26 corresponding to it; therefore, it is not limited here.

[0026] In some embodiments, the bracket 21 may include a mounting plate 211, a hanging plate 212, and a fixing plate 213. The top of the hanging plate 212 is connected to the mounting plate 211, and the fixing plate 213 is connected to the bottom of the hanging plate 212. The mounting plate 211 is used to mount to the processing head 10. The detection element 22 is disposed on the hanging plate 212. The drive assembly 23 is fixed to the fixing plate 213. The guide shaft 25 is movably disposed on the fixing plate 213. The detection element 22 is located in the direction of movement of the guide shaft 25 so as to drive the trigger 26 to trigger the detection element 22.

[0027] Furthermore, the top of one side of the mounting plate 212 is vertically connected to the mounting plate 211, and the fixing plate 213 is vertically connected to the bottom of one side of the mounting plate 212. That is, the mounting plate 211 and the fixing plate 213 are respectively connected to the two sides of the mounting plate 212. With this design, the processing head 10 is located on one side of the mounting plate 212 and can move in a direction parallel to the mounting plate 212, while the guide rod and drive assembly 23 are located on the other side of the mounting plate 212 and can move in a direction parallel to the mounting plate 212. This avoids interference between the movement of the processing head 10 and the guide rod and drive assembly 23.

[0028] The mounting plate 211 is provided with a mounting opening 2111 whose shape is adapted to the processing head 10. The mounting plate 211 is sleeved on the outside of the processing head 10 through the mounting opening 2111 to be installed on the processing head 10.

[0029] The bracket 21 may also include a linear bearing 216, which is mounted on the fixed plate 213. The guide shaft 25 passes through the linear bearing 216 and is movably connected to the fixed plate 213. Direct bearing mounting of the guide shaft 25 reduces friction, energy consumption and heat generation, improves motion accuracy and repeatability, enhances heavy load and anti-overturning moment support, extends service life, reduces maintenance costs, and simplifies design with standardized components, making it suitable for high-precision, high-speed, and heavy-load applications.

[0030] In some embodiments, considering that smoke and splashes during the cutting process could affect the service life of the drive assembly 23 and guide shaft 25, the bracket 21 further includes a dust cover 214 and an isolation plate 215. The dust cover 214 is fixed above the fixing plate 213, covering the portions of the drive assembly 23 and guide shaft 25 located above the fixing plate 213. The isolation plate 215 is fixed below the fixing plate 213, separating the portions of the drive assembly 23 and guide shaft 25 located below the fixing plate 213 from the processing head 10. With this design, the dust cover 214 can prevent smoke and splashes from reaching the portions of the drive assembly 23 and guide shaft 25 located above the fixing plate 213, and the isolation plate 215 can prevent smoke and splashes from reaching the portions of the drive assembly 23 and guide shaft 25 located below the fixing plate 213.

[0031] In some embodiments, the drive assembly 23 is equipped with a pressure regulating valve and a control component. The pressure regulating valve is used to adjust the pressure in the air passage of the drive assembly 23 to control the extension and retraction force of the drive assembly 23, and the control component is used to control the extension and retraction actions of the drive assembly 23. With this design, the extension pressure of the drive assembly 23 is adjusted by the pressure regulating valve to make the extension force of the drive assembly 23 less than the force of the machining head 10 moving vertically downward. After the ball contact 243 contacts the workpiece to be processed, the machining head 10 continues to descend, causing the drive assembly 23 to retract.

[0032] The control component can be a pneumatic valve, hydraulic valve, or electric valve, etc., and is not limited to it. In this embodiment, the control component is a central control solenoid valve.

[0033] In some embodiments, there are two guide shafts 25, both movably mounted on the bracket 21 and located on opposite sides of the drive assembly 23. The trigger 26 is mounted on one of the guide shafts 25, and the detection element 22 is located on one side of the guide shaft 25. Using two guide shafts 25 can improve the stability of the movement of the pushing member 24.

[0034] In some embodiments, to make the machining head ranging assembly 20 applicable to machining heads 10 with different focal length cutting distances, the trigger 26 is movably connected to the guide shaft 25. The trigger 26 can be controlled to move relative to the guide shaft 25 to adjust the relative position of the trigger 26 and the bracket 21. With this design, the trigger 26 can move and be fixed at any position on the guide shaft 25, realizing the adjustment of different focal length cutting distances to meet different usage requirements.

[0035] In some embodiments, the pusher 24 may include a push-out portion 241 and a squeeze portion 242. The top of the push-out portion 241 is connected to the movable end of the drive assembly 23, and the squeeze portion 242 is connected to the bottom of the push-out portion 241. The squeeze portion 242 is used to contact the workpiece to be processed. The driving force of the drive assembly 23 is transmitted to the bottom squeeze portion 242 through the top push-out portion 241 so that the push-out portion 241 and the squeeze portion 242 are pushed out. Under the squeeze of the workpiece to be processed, the squeeze portion 242 transmits pressure to the push-out portion 241. The push-out portion 241 compresses the drive assembly 23 so that the drive assembly 23 retracts.

[0036] Furthermore, the extrusion section 242 is a frame structure with an inner diameter larger than the outer diameter of the processing head 10. The inner side of the frame of the extrusion section 242 is used for the processing head 10, which moves toward the workpiece to be processed, to pass through. With this design, the frame structure extrudes the workpiece to be processed, which can improve the stability of the extrusion section 242 extruding the workpiece to be processed, so that the workpiece to be processed is subjected to uniform force and is stably positioned.

[0037] For example, the extrusion part 242 has a square frame structure. It is understood that in other optional embodiments, the extrusion part 242 may also have a circular frame, a diamond frame, etc., as long as the processing head 10 can pass through it. It is not limited here.

[0038] Furthermore, the pusher 24 may also include a ball-head contact 243, which is located in the pressing section 242. The arc-shaped surface of the ball-head contact 243 faces the workpiece to be processed and is used to press the workpiece. With this design, compared to surface contact ranging, the ball-head contact 243 can avoid the problem of inaccurate ranging caused by unevenness of the cut plate surface, thus improving the accuracy of ranging.

[0039] For example, there are four ball head contacts 243, which are respectively disposed on the four square borders of the extrusion part 242.

[0040] The following is a detailed description of the distance measurement process of the processing equipment:

[0041] The drive assembly 23 is extended by the control component, and the pusher 24 moves from above the nozzle of the processing head 10 to below the nozzle of the processing head 10, that is, the ball contact 243 is below the nozzle of the processing head 10. After the drive assembly 23 extends to the position, the processing head 10 is driven to move vertically downward. The extension pressure of the drive assembly 23 is adjusted by the pressure regulating valve so that the extension force of the drive assembly 23 is less than the force of the processing head 10 moving vertically downward. When the ball contact 243 contacts the workpiece to be processed, the processing head 10 continues to descend. The workpiece to be processed squeezes the pusher 24, and the pusher 24 compresses the drive assembly 23, causing the drive assembly 23 to retract. When the drive assembly 23 retracts a certain distance, the trigger block triggers the detection element 22. The detection element 22 detects that the processing head 10 has moved to the position, the processing head 10 stops descending and records the height. After the distance measurement is completed, the drive assembly 23 retracts, and the pusher 24 returns to the position above the nozzle of the processing head 10.
